Psychophysical theory
WebPsychophysics is the subfield of psychology devoted to the study of physical stimuli and their interaction with sensory systems. Psychophysical tasks have been extensively used … WebPsychophysical functions can often be described as power functions of physical intensity. 2,4,–6 Power functions quantify the extent to which the response is a nonlinear function of the input quantity. They take the form f ( x )= kxa. Figure 2.1 Open in new tab Download slide Magnitude estimation for patches of different light intensity.
